It's hard to tell where the cause of the problem is. Trougbleshooting this problem will help, though. To begin troubleshooting, I'd recommend the following:
1. Is there any conflict (yellow exclamation mark) shown in Device Manager on the Sound Controller? If so, remove the currently installed sound driver and attempt the install from within Safe Mode.
2. If the problem continues, please, test with the most current audio driver, which is posted (Click here).
1. There's no conflict shown in the device manager, nothing has a yellow exclamation point.
2. I've tried to install the current audio driver, but the IDT installer says it won't work with my hardware now.
Even though there's no conflict shown among the Device Manager, should I try uninstalling the "ATI function driver for HD audio - ATI AA01"? I had previously uninstalled it and tried using the kb835221 driver (although I had deleted the kb888111 driver earlier and now can't reinstall it because I have service pack 3).
I did a system restore to a point 1 week before these troubles began. It rolled me back to Service Pack 2, but didn't restore my audio. It did let me reinstall the kb888111 driver, but that hasn't fixed the problem.
The IDT Audio Control Panel in my control panel was restored, but when I try to run it it just says the "IDT Audio driver is inaccessible." I've tried restarting the system and that doesn't help. I'm going to try reinstalling Service Pack 3 and the other software but I have low hopes for that.
Edit: I tried Service Pack 3, no luck. And I tried using my Intel driver disc to reinstall the IDT software, but it claimed that it was already installed. I tried to install it anyway and now it's gone. I think perhaps that wasn't the problem.
I'm going to totally reformat and reinstall WinXP from scratch, I'll see if that fixes things. If it doesn't, I fear I'll have to buy a cheap sound card and use that, because I would assume its a hardware problem with the onboard audio. I'll report back soon...
Update: I did a clean install of XP, including reformatting, and it still will not recognize any sound device. I will try these speakers on my roommate's laptop to see if it is a hardware failure there, or on the motherboard.
I've tried using Intel's automatic driver updater, http://www.intel.com/support/motherboards/desktop/detect.htm , and it recommended the AUD_ALLOS_6224.3_PV_IDTGUI_V182. I downloaded it but it won't install, it says it isn't compatible with my hardware.
Looking at Intel's troubleshooting page, http://www.intel.com/support/motherboards/desktop/sb/CS-020642.htm#solution , it says I should have either IDT, Realtek, or ADI Soundmax. I tried installing each of those but only Realtek would install its drivers, and they haven't made a difference. I also tried unplugging the case's front audio ports from the mobo, because this model supposedly has a problem when they're used (that's when it stopped working for me, when I tried to put headphones in the front port) but that didn't work.
I tested the speakers on another device and they work fine. It looks like I'll have to get a cheap soundcard to bypass the motherboard entirely.
How did re-formatting and re-installing Windows* XP from scratch go?
Note: I remind you the Critical Driver Installation order for Windows* XP is found here:
As for the latest driver, applicable for the Intel(R) Desktop Board DP45SG under Windows* XP, is found here.
Hi Salem. Unfortunately a clean install of XP after reformatting did NOT solve the problem.
I've tried installing those drivers you mention, and the IDT software simply says "failed" after installation is attempted.
At this point I am going to buy a cheap sound card to bypass the motherboard entirely, and hope that works.
